Tuna and Spinach Cannelloni

I haven't posted anything for awhile now, so here is an old receipt from Sainsbury's.

 

Ingredients

250g of Lasagne Sheets
1 Onion
125g of Mozzarella Cheese
500g of Passata Sauce
370g of Tuna Chunks
700g of Frozen Spinach

Seasoning to taste
Serves 4

Method

1. Preheat the oven to 180oC, gas mark 4. 
2. Gently shallow fry the onion, peeled and finely chopped, until softened. Add the tuna chunks and the frozen spinach. Heat until the spinach has broken up and the mixture is piping hot. Season with a little salt and pepper to taste.
3. Meanwhile, Cut all the lasagne sheets in half to make squares. Place 2 tablespoons of the mixture onto the end of each square and roll up so you have 12 cannelloni. Place along the bottom of a large ovenproof dish.
4. Pour the passata over the cannelloni. Drain and tear into pieces the mozzarella cheese, sprinkle over cannelloni.
5. Bake for 30 minutes, then grill for 2-3 minutes until top is golden and the cheese is bubbling. 

Notes

Mozzarella is a full-fat cheese, so for those seeking a low-fat option a number of different cheeses can be used, Ricotta is just one such option.
